CI / CD Pipeline

NOTE (forward-looking): image registry path reflects the post-rename state. Today's pipeline pushes azaion/flights:${BRANCH}-arm. Rename tracked under Jira AZ-EPIC child B10 (Dockerfile + Woodpecker + suite compose).

Source

./.woodpecker/build-arm.yml (single CI file). One job: build + push the container image.

when:
  event: [push, manual]
  branch: [dev, stage, main]

labels:
  platform: arm64

steps:
  - name: build-push
    image: docker
    environment:
      REGISTRY_HOST:  { from_secret: registry_host }
      REGISTRY_USER:  { from_secret: registry_user }
      REGISTRY_TOKEN: { from_secret: registry_token }
    commands:
      - echo "$REGISTRY_TOKEN" | docker login "$REGISTRY_HOST" -u "$REGISTRY_USER" --password-stdin
      - export TAG=${CI_COMMIT_BRANCH}-arm
      - export BUILD_DATE=$(date -u +%Y-%m-%dT%H:%M:%SZ)
      - |
        docker build -f Dockerfile \
          --build-arg CI_COMMIT_SHA=$CI_COMMIT_SHA \
          --label org.opencontainers.image.revision=$CI_COMMIT_SHA \
          --label org.opencontainers.image.created=$BUILD_DATE \
          --label org.opencontainers.image.source=$CI_REPO_URL \
          -t $REGISTRY_HOST/azaion/missions:$TAG .                  # post-B10
      - docker push $REGISTRY_HOST/azaion/missions:$TAG             # post-B10
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Triggers

Trigger	Branch filter	Outcome
push	dev, stage, main	Build + push the corresponding ${BRANCH}-arm image tag
manual	any of dev, stage, main	Same as push — used for rebuilding without a code change (e.g., after a base-image security patch)
pull_request, other branches	—	Not built today. Feature branches do not produce images

Runner / platform

• labels: platform: arm64 — the pipeline runs on an ARM64-labeled Woodpecker runner. The build is therefore native for the ARM64 image variant (no QEMU). The Dockerfile's --platform=$BUILDPLATFORM for the build stage ensures the SDK image matches the runner's architecture.
• For the (currently absent) AMD64 variant a second pipeline file (build-amd.yml) on an AMD64-labeled runner would be the natural pattern.

Secrets

Secret	Source	Purpose
registry_host	Woodpecker secret store	Hostname of the suite's container registry (Caddy-fronted Gitea Container Registry per ../../../suite/_docs/00_top_level_architecture.md)
registry_user	Woodpecker secret store	Service account that has push rights to azaion/missions
registry_token	Woodpecker secret store	Personal access token for the service account

docker login is piped via stdin (--password-stdin) — token never lands on the command line or in process listings.

OCI labels emitted

Three standard OCI labels are baked into every published image:

Label	Value	Source
org.opencontainers.image.revision	$CI_COMMIT_SHA	Git commit driving this build
org.opencontainers.image.created	$BUILD_DATE (ISO 8601 UTC)	date -u +%Y-%m-%dT%H:%M:%SZ at build time
org.opencontainers.image.source	$CI_REPO_URL	Suite Gitea repo URL

These let docker inspect answer "which commit and when?" without consulting the registry's metadata.

What the pipeline does NOT do (carry-forward improvements)

• No dotnet test step — there is no test project in the repo today. Tracked in ../../../suite/_docs/_process_leftovers/2026-04-22_ci-unit-test-lane-missing-projects.md. When a tests/Azaion.Missions.Tests/ sibling lands (autodev existing-code Steps 5–7), the natural insert is a name: test step that runs dotnet test --collect "XPlat Code Coverage" against the build before the docker step.
• No security scan — neither container scanning (Trivy / Grype on the published image) nor source scanning (CodeQL / Semgrep) is wired. Suite-level concern; out of this Epic.
• No migration check — the migrator runs at app startup (Flow F6). A CI-time "does the migrator's DDL parse cleanly against an empty PG" smoke test is the next-cheapest safety net once tests exist.
• No SBOM — docker buildx --sbom would surface base-image CVEs at registry-push time. Carry-forward.
• No image-signing — Notary v2 / cosign is not wired. Carry-forward; suite-wide concern.
• No multi-arch matrix — only arm64 builds today (see containerization.md § Multi-arch limitation).

Pipeline run-time characteristics

• Single step, single image. Typical wall-clock time: 2–5 minutes on the suite's ARM64 runner (most of it dotnet publish + the runtime image layer pull).
• No caching layer between builds today. dotnet restore re-downloads NuGet packages on every run. A persistent ~/.nuget volume on the runner would shave ~30 seconds per build.

Failure modes

Failure	Symptom in Woodpecker	Recovery
dotnet publish fails	Build step fails with compilation errors	Standard — fix source, push again
Registry login fails (rotated token)	docker login exits non-zero	Rotate registry_token in Woodpecker secrets
Registry push rate-limited	docker push 429	Retry the manual run; rare in practice with Gitea-hosted registry
ARM64 runner offline	Pipeline waits in queue	Bring the runner back online; pipeline auto-resumes
